COMBINATION-LOCK.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed March 24, 1915. Serial No. 16,637.

To all whom it may concern:

Be it known that I, THOMAS CAPPARELLA, a subject of the King of Italy, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Combination-Locks, of which the following is a full, clear, and exact specification.

This invention relates to combination locks, especially designed for trunks, boxes, desks and handbags.

The object of the invention is to produce a lock of this kind which is simple in construction and inexpensive to manufacture.

A further object is to make the look more compact so that it can be applied to handbags as well as larger articles.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more specifically defined in the claim at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views: Figure 1 is a plan view of a lock constructed substantially in accordance with this invention, the hasp-plate being in locked position. Fig. 2 is a front elevation. Fig. 3 is a central vertical section of Fig. 1, drawn to an enlarged scale. Fig. 4 is a detailed view showing the tumbler disks in section on the spindle. Fig. 5, 6 and 7 are detailed plan views of the tumbler disks, and Fig. 8 is a detailed View of the hasp, the plate which carries the same being shown in section.

The lock 1 comprises a casing 2 having projecting tabs 3 for securing it to one of the parts to be locked together. Within the casing and projecting from the top thereof is a spindle 4 carrying three tumblers 5, 6 and 7, each being in a form of a disk having a notch or groove 8, 9 and 10. respectivelv, in its peripherv. The tumbler 7 is rigidly connected to the spindle, while the tumblers 5 and 6 are loosely mounted thereon. Said tumblers are suitablv spaced apart and carry pins adapted to strike one another for the purpose of turning the loose disks to bring their notches into alinement with the notch in the fixed disk. Said fixed disk 7 has an upwardly projected pin 11 arranged in a path of a depending pin 12 on the disk 6, and the latter disk has a pin 13 on its upper surface arranged in a path of a depending pin 14: on the disk 5. The disk 7 may also be provided with a Second pin 15 also arranged in the plane with the pin 12 and adapted to engage it on the opposite side from that with which the pin 11 contacts, for insuring a movement of the disk 6 in less than an entire revolution of the disk 7.

The spindle 4: carries a milled head or button 16 on its upper projecting end for manipulating the tumblers. The spindle also carries a pointer 17 located near the upper surface of the casing 2. A dial 18 is arranged on the upper surface of the casing just below the pointer.

The bottom of the casing 2 is provided with an opening 19 through which the hasp 20 passes for interlocking engagement with the tumblers, said hasp having notches 21, 22 and 23 to receive the peripheral portions of the disks or tumblers 5, 6 and 7, respectively. The hasp is carried by a plate 24: adapted to be fastened to one of the two parts to be locked together, it being understood that the lock 1 is to be attached to the other one of these parts.

The location of the pins 11, 12, 13 and 14 with respect to the dial and pointer will, of course, determine the combination necessary for bringing the groove or notches in all three tumblers into alinement with the opening 19 in the casing or, in other words, in line with the hasp 20, to permit said hasp to be inserted or withdrawn. When the hasp is inserted and the tumblers are turned with their notches out of line with the opening 19 and the hasp, the peripheral portions of the tumblers will engage the notches 21, 22 and 23 in the hasp and lock the same in the casing, as illustrated in Fig. 3. By changing the relative positions of the pins 11, 12, 13 and 14, a different combination may be used, so that locks may be made in accordance with this invention with a great variety of combinations, each diiferent from another if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

A. combination lock comprising a casing adapted to be secured to the lid of a trunk, said casing having a vertically disposed spindle journaled therein and projecting from its top face, tumblers on the spindle to enter the opening in the bottom of the Within the casing, an operating knob on the casing and interlock with the tumblers, said projecting end of the spindle, said casing hasp being arranged parallel to the spindle 1 having an opening in its bottom face in line and at right angles to the tumblers.

5 'With the tumblers, and a hasp plate adapted In testimony whereof I have signed my to be secured to the body of a trunk and name to this specification. having a vertically projecting hasp adapted THOMAS CAPPARELLA.
